These data were used by Kuhn et al. (2015) to investigate how conclusions about predator-prey relationships change with increasing temporal disparity between predator tracking periods and prey surveys. Northern fur seals (n = 20) from St. Paul Island (Alaska, USA) were equipped with satellite tracking transmitters and time-depth recorders from July to October 2006. Fur seal dive and movement metrics were examined in relation to the relative abundance of the fur seals’ primary prey, walleye pollock (Gadus chalcogrammus), reported from the annual eastern Bering Sea groundfish survey. Relationships between foraging behavior metrics and prey abundance were examined within the Bering shelf survey grid cells at three time scales: within 2 weeks of the prey survey, within 1 month, and over the northern fur seal reproductive season (>4 months).

This database contains information on pup production estimates, adult male counts and harvests (commercial and subsistence) for the Pribilof Islands of St. Paul and St. George. Methodology for the data collection for adult males and animals harvested has been consistent over time. The estimation of pup production has gone through an evolution of methodology that is indicated in the database. Cite dataset as: Alaska Ecosystems Program. 2019.

This database contains information on individual sea lions that were marked or handled from 1985-2018. Individuals were handled for various projects including vital rate, telemetry and health studies. Many of the animals were either flipper tagged or branded. Capture techniques vary including; hand-capture of pups, hoop netting and underwater captures of juveniles, dart-delivered sedation of adult females, and floating pen capture of sub-adult and adult males. This dataset is associated with NMFS InPort Metadata Record #17918

The Marine Mammal Laboratory (MML) Food Habits Reference Collection, containing over 1000 specimens of cephalopod beaks and fish bones and otoliths, is used to identify undigested prey remains found in scats or stomachs of stranded or incidentally taken pinnipeds and cetaceans. Marine mammal food habits data are used in conjunction with satellite telemetry and dive records to better understand foraging behavior and prey selection. This information is critical to understanding how commercial fisheries and changing environmental conditions impact these animals.

The Food Habits Collection includes fish and cephalopod species that are commonly consumed by pinnipeds along the Pacific Northwest coast and in Alaska, but we are in the process of adding other potential prey species and specimens to fill unrepresented size ranges. We are very appreciative of NMFS/AFSC/RACE fisheries biologists, the Alaska Department of Fish and Game and the University of Washington for their ongoing donations to our collection. With the help and cooperation of researchers such as these, our collection continues to grow in size and usefulness.

The Marine Mammal Food Habits Reference Collection is an important research tool within NMML, and is also used several times a year by graduate students and researchers from universities, government agencies and private institutions. These collections have contributed to food habits research on Magister armhook squid, Northern fulmar, Newells shearwater, Hawaiian petrel, river otters and marine mammals. The collections are also used by archeologists to identify fish and mammal bones found in Native American middens from Alaska to Mexico.

The database is comprised of a table detailing specimens and associated data and measurements for fish and cephalopod soft tissue and hard parts contained within the reference collection.

This dataset contains information regarding the sighting and capture of Steller sea lions marked in Alaska from 1987 to 2014. Marks are seen and documented in a variety of ways; remote cameras, dedicated vessel- and land-based surveys, recaptures of Steller sea lions, aerial survey photographs, strandings, and opportunistic sightings sent in from the public.

These data were used for an analysis of Steller sea lion pup health and condition by Lander et al. (2013). Serum chemistry and hematological values were measured by analysis of blood samples taken from 1,231 Steller sea lion pups (
